SEWER AND DRAIN-TILE OUTLET PROTECTOR.

Specification of Letters Patent.

Patented July 2'7, 1909 Application filed March 9,1909. SeriaI'No.482,285.

To all whom it may concern:

Be it known that we, OLE A. TENOLD and JOHN A. TENOLD, citizens of theUnited States, residing at Northwood, in the county of Worth and Stateof Iowa, have invented certain new and useful Improvements in Sewer andDrain-Tile Outlet Protectors, of which the following is a specification.

Our invention relates to the protection of the outlets of drain tilesand sewers from vermin and has for its object the provision of a devicethat is capable of being readily attached to and removed from the draintile, that is reasonable in cost of manufacture, and effective inoperation.

Our invention consists essentially of an open sleeve having flanged endssecured together by bolts, the outer end of the sleeve being oblique,and having an elliptically shaped gate mounted therein and pivoted onthe forwardmost boltused to secure the sleeve on the tile.

Our invention will be described in detail hereinafter and illustrated inthe accompanying drawings in which Figure l is a side view of the end ofa drain tile or sewer outlet with our improved protector in placethereon, Fig. 2, a top plan view, and Fig. 3, a front view.

In the drawings similar reference characters indicate correspondingparts in the several views.

A indicates a sewer pipe or drain tile to which our improved outletprotector is removably and replaceably secured, said protectorconsisting of an open sleeve 1 having its meeting edges formed withflanges 2 through which are secured bolts 3 to hold the sleeveinposition on the end of the pipe or tile A. The delivery end of sleeve 1is formed obliquely as shown at A and has a gate 5 therein pivotallysecured by means of hinge 5 to the forwardmost of the bolts 8. The gate5 is made elliptical in shape and provided with a number of holes 6 thatwill permit the egress of a moderate flow of water from the tile or pipeA, without disturbing the gate, but should the flow increase the gatewill be raised thereby to permit it to flow and when, the flow lessensthe gate will return to its normal position by gravity and serve toprevent vermin from entering the tile or pipe.

7 indicates a plate secured to the gate 5 and having its free endsecured and extended around hinge 5*" and outwardly to form a stop tolimit the upward movement of'the ate.

I 8 indicates hooks on the sides of the sleeve 1 to which are securedanchors consisting of plates 9 and chains or cables 10 connecting theplates and the hooks.

Having thus described our invention what we claim is 1. A sewer anddrain tile outlet protector consisting of a sleeve open at one side andhaving outwardly extending flanges, said sleeve being adapted to fitover the outside of the end of a drain tile, bolts secured through theflanges to adjust the sleeve on the tile, and a gate pivotally securedto the end bolt between the flanges.

2. A sewer and drain tile outlet protector consisting of a sleeve openat one side and having outwardly extending flanges, said sleeve beingadapted to fit over the outside of the end of the drain tile, boltssecured through said flanges to adjust the sleeve on the tile, a gatepivotally secured to the forwardmost bolt, and a stop extending from thepivotally secured portion to engage the end of the drain tile and limitthe upward swing of the gate.

3.'A sewer and drain tile outlet protector consisting of a sleeve shapedto fit over the outside of the end of the sewer or drain tile and havingoutwardly extending flanges, bolts secured through said flanges, thefront of the sleeve being inclined, and a perforated gate pivotallysecured to the forwardmost bolt and resting in the inclined opening inthe sleeve, said gate being elliptical in shape to fit said opening.

4. A sewer and drain tile outlet protector consisting of a sleeve openat its top and having outwardly extending flanges, said sleeve beingadapted to fit over the outside of the end of the draintile and havingits front end inclined, bolts secured through said flanges to adjust thesleeve on the tile, a gate mounted in the inclined opening of the sleeveand hinged to the forwardmost bolt, and a stop extending from thepivotally secured portion to engage the end of the drain tile and limitthe upward swing of the gate.

In testimony whereof we hereto aflix our signatures in the presence oftwo witnesses.

OLE A. TENOLD. JOHN A. TENOLD. Witnesses:

R. H. DOUGLAS, W. A. WESTFALL.
